SOLE-EDGE TRIMMER.

SPECIFICATION forming part of Letters Patent No. 268,858, dated December12, 1882.

Application filed April 13, 1882. (Model.)

To all whom it may concern:

y Be it known that I, BENJAMIN D BoovER, of Haverhill, in the county ofEssex and State of Massachusetts, have invented a newand useful Improvenientin Sole-Edge Trimmers for Boots and Shoes, of which thefollowing is a specification. A

The object of my' invention is to combinein one tool the meansoftrimming around, a beveled, or square edge, as desired, of a boot orshoe sole.

The invention consists of a guard of peculiar construction, used inconnection .with another guard and a cutter, so that by a simple changeof location ofthe parts the cutter caube made to trim aboot or shoe solewith a round, a beveled, or square edge.

In the accompanying drawings, Figure 1 repiesents a side view of thetool when arranged to cut a round edge. Fig. 2 is a front view of same,looking toward the cutting-edge of the knife. Fig. 3 represents a frontView of the tool arranged for cutting a beveled ed ge. Fig.`

4 shows the tool arranged for cutting asquare edge; Fig. 5, views ofthecurved knife. Fig. 6 is a view of the straight knife; Fig. 7, viewsofthe back guard Fig. 8, views of the guard; Fig. 9, views of theangle-piece.

A is a handle, into which is fitted aknife or cutter, B, constructedwith a curved portion at or near the upper end, as shown in Fig. 5.

C is what I term a back guard, which is curved at its upper end, asshown separately in Fig. 7, so as to allow the shavings to escape freelyfrom the cutter, and the end c projects over, as shown, against whichprojecting end the cntterB abuts; or it may be fitted in a notch orgroove made in the said projecting edge c. The cutter B has a slot, b,at one side, throughwhich passes a screw, d, by means of which and thewasher @the guard O is secured to the cutter B, the slot admitting of auadjustment of guard C to cut more or less deep into the sole-edge. Theguard C is provided with a projecting edge, g, against which the edgeofthe cutter lits.

At one side ofthe guard Cisarranged aguard, E, (Shown in detail in Fig.S.) This guard E is provided with a curved portion, h, which acts as theguard, and a straight portion,j, which serves as a guide. The guard E issecured in position by means of screws fj' entering the guard C andpassing through the holese, which are made large enough to allow of theguard E being adjusted in any desired position relatively to thecutting-edge ofthe cutter B. Ou the opposite side of the back guard, C,is secured the angle-piece F, which serves as a bearing to the back ofthe curved cutter B.

In Fig. 3 the tool is showu'as arranged for cutting a beveled edge, inwhich case the straight knife or cutter B is'nsed, as shown in Figs. 3and 4, and abuts against the under side of the portion c, or may betittedin a notch in the same, and is held against the projection g, theposition of the angle-piece F being changed so as to overlap the rearedge of the cutter B', and the guard E being in the same position aswhen the tool is used with the curved cutter B.

In Fig. 4 the tool is shown as arranged for cutting a straight edge, theonly change required from the position shown in Fig. 3 being thereversing of the guard E, so as to bring the straight pnrtj againstorne'ar the cuttingedge of the cutter B', as shown.

What I claim as my invention is-' y A sole-edge trimmer constructed witha back guard,0, carrying the reversible guard E, having one straightside, j, and one curved side, h, and the angle-piece F, and adapted toaccommodate a straight or a curved knife, substantially as and for thepurpose set forth. In testimony whereof' I have signed my name to thisspecification in the presence of two subscribing witnesses.
